“But the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you.”
King James Version (KJV)
1Pe 1:25 The word of the Lord endureth forever. Like its author it is eternal and never loses its power. And this is the word which by the gospel is preached unto you. That word was the gospel, the very gospel preached to them by Paul and his fellow ministers.
